Does it make a buzzing noise when you turn on the ig?

If you have the full fat 33bhp jobbie (with noise)you may have landed on a full power version that was never restricted or de restricted by yamaha, as to restricting it its Not quite that simple. you will need to re-restrict it properly, as in remove the powervalve computer and i believe swap the cdi, peg the valve in the restricted position, correct the carburation change the carb top and restrict the exhaust effectively.

If you have the garage quicky method i would just ride it cos what you think is 30 odd hp will really be about 18 but it comes as a big slap at about 7000rpm.

Did no end of these as an oily youth in denim, the TZR was the big thing in my day (88) and i could wind em up pretty good in the end, could never afford one m'self.

Sorry mate the powervalve isnt a magic button, youve been told its been profesionally tuned but no-one fitted the powervalve electrics, sorry but someone is jerking your chain.

If all you do is set the valve low, the power will go low and all the carberation goes to ratshit and it wont rev out. It will wheelie everywhere (for about 10min).

They are either restricted or not you can't really turn them up and down like a light. The only thing to do is fit a std pipe, std jets and lock the valve back where it should be, or leave well alone and be a bit naughty.
